摘　　要：通过对不同厌氧发酵技术比较,提出车库式干发酵技术具有原料适应性强、处理负荷大、过程能耗低、产物后处理简单且基本无废水排放等特点;通过对我国首次实施干湿耦合厌氧技术的河北华电丰宁生物质沼气综合利用项目分析计算,项目投产后可年减排二氧化碳34734 t,可实现土壤固碳1175.5 t;丰宁创新模式对各类可降解有机废弃物接纳性最高、沼液排放量最少,该集成技术在我国生物燃气产业,尤其是我国生物质资源综合利用产业具有较好的推广潜力。Through the comparison of the different anaerobic digestion technologies,the paper proposes the advantages of the garage type dry fermentation technology are widely adaptable of raw material,large load treatment capacity,low energy consumption,simple digestate treatment and no waste water emission.This technology covers a relatively large area,and the operating environment is relatively poor,which required to focus on breaking through above technical difficulties in the subsequent development process.Through the analysis and the calculation of the Hebei Huadian Fengning biomass gas comprehensive utilization project,which is the first industrial practice of the integration of the dry and wet fermentation biogas production technology,the result shows the project will reduce the carbon dioxide 34734 t·a-1 and storage the carbon 1175.5 t·a-1.The Fengning innovative model of anaerobic biogas production by the integration of dry and wet fermentation has the highest acceptability for all kinds of degradable organic waste.This integrated technology has a good potential promotion for biogas industry,especially in the comprehensive utilization of biomass resources in China.
